Weightlifting, also called Olympic-style weightlifting, or Olympic weightlifting, is an athletic discipline in the modern Olympic programme in which the athlete attempts a maximum-weight single lift of a barbell loaded with weight plates.
The two competition lifts in order are the snatch and the clean and jerk. Each weightlifter receives three attempts in each, and the combined total of the highest two successful lifts determines the overall result within a bodyweight category. Bodyweight categories are different for male and female competitors. A lifter who fails to complete at least one successful snatch and one successful clean and jerk also fails to total, and therefore receives an "incomplete" entry for the competition. The clean and press was once a competition lift, but was discontinued due to difficulties in judging proper form.
In comparison with other strength sports, which test limit strength (with or without lifting aids), Weightlifting tests aspects of human ballistic limits (explosive strength); the lifts are therefore executed faster—and with more mobility and a greater range of motion during their execution—than other strength movements. Properly executed, the snatch and the clean and jerk are both dynamic and explosive while appearing graceful, especially when viewed from a recording at a slowed speed.
While there are relatively few competitive Olympic weightlifters, the lifts performed in the sport of weightlifting, and in particular their component lifts (e.g. squats, deadlifts, cleans), are commonly used by elite athletes in other sports to train for both explosive and functional strength.
The sport is controlled by the International Weightlifting Federation (IWF). Based in Budapest, it was founded in 1905.
Athletes compete in a division determined by their body mass. There have been eight male divisions and eight female divisions since 2017.

In each weight division, lifters compete in both the snatch and clean and jerk. Prizes are usually given for the heaviest weights lifted in each and in the overall—the maximum lifts of both combined. The order of the competition is up to the lifters—the competitor who chooses to attempt the lowest weight goes first. If they are unsuccessful at that weight, they have the option of reattempting at that weight or trying a heavier weight after any other competitors have made attempts at the previous weight or any other intermediate weights. The barbell is loaded incrementally and progresses to a heavier weight throughout the course of competition. Weights are set in 1 kilogram increments. When a tie occurs, the athlete with the lower bodyweight is declared the winner. If two athletes lift the same total weight and have the same bodyweight, the winner is the athlete who lifted the total weight first.
